A business must evolve with the times, and the Ringling Bros. and Barnum & Bailey circus is no different. The Greatest Show on Earth has managed to entertain children of all ages through the Roaring Twenties, the Great Depression and the advent of television, movies and the information age.

Certain long-held traditions, such as traveling by train, remain. The circus train is more than a mile long and serves as living quarters for hundreds of support staffers and performers, who will stage the new “Built to Amaze” show at the Valley View Casino Center tonight through Sunday.

Circus folk call it a moving town without a ZIP code, and it’s equipped with a nursery, a school and a restaurant that is historically known as the “pie car.”

“We have traveled by rail for decades,” says boss clown “Taylor the Tailor” Albin. “We each have a mini apartment on the train, our own private room. When the train is moving, we are able to walk from one car to another.”

Interacting with an international staff also remains characteristic of circus life.

“Every day we come into contact with a minimum of 10 different cultures, and it’s not uncommon to be invited into a room to sample someone’s native food,” says Albin, who has acquired a taste for Russian, Moroccan, Hungarian and Chinese cuisine.

“We have brought amazing acts from all over the world to an American audience.”

The construction-themed “Built to Amaze” tour includes the Danguir Troupe, a high-wire act from Morocco; trampoline tumblers from the Ukraine; and the King Charles Troupe, basketball-playing unicyclists from the Bronx. Chilean-born animal trainer Tabayara Maluenda inspires pachyderms in hard hats to perform and commands a team of tigers to stand on their hindquarters.

One of Albin’s favorite segments is performed by the Russian duo Alex and Irina Emelin, who also serve as project managers for the show.

“They have an amazing dog act — oodles of poodles, I like to say,” says Albin. “They have big and little poodles that do dances and flips, and because they are big fans of American movies, the dogs are named after celebrities.”

In more recent times, the Ringling Bros. and Barnum & Bailey Circus has implemented animal conservation and educational outreach programs. The current size of the circus, with four touring shows and its varied spectacles, has demanded the need for assigning individuals to oversee specific acts — hence the job of “boss clown.”

Albin, 26, graduated from Lee University in Tennessee and started working for Ringling in 2009.
